Understanding Histamine Intolerance
Histamine intolerance occurs when there is an imbalance between accumulated histamine and the body's ability to break it down. Unlike a food allergy, histamine intolerance is a digestive issue where the body cannot properly process histamine from foods.
What is Histamine?
Histamine is a chemical compound that plays important roles in your immune system, digestion, and nervous system. It's naturally present in many foods and is also produced by your body.
Common Symptoms
- Headaches and migraines
- Digestive issues (bloating, diarrhea, abdominal pain)
- Skin problems (hives, eczema, itching)
- Respiratory issues (nasal congestion, asthma-like symptoms)
- Irregular heartbeat or rapid heart rate
- Anxiety and sleep disturbances
- Fatigue
Causes of Histamine Intolerance
The primary cause is a deficiency in diamine oxidase (DAO), the enzyme responsible for breaking down histamine in the digestive tract. Other factors include:
- Genetic predisposition
- Gut health issues
- Certain medications that block DAO
- Bacterial overgrowth
Diagnosis and Treatment
Diagnosis can be challenging as symptoms overlap with other conditions. Treatment typically involves following a low-histamine diet and addressing underlying gut health issues.
